Title: Water heater
Inventor: WATANABE HISAYASU
IPC: F24H1/10
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To perform operation such that a heat insulation function to insulate the heat of water in a heat exchanger to a value within a heat insulation temperature range in preparation for supply of hot water by effecting combustion of a burner in no water flow state is brought into an ON or an OFF state at a proper timing. SOLUTION: When some operation for variation of a set temperature and the like is effected by a remote control unit 60, it is estimated that this apparatus has a will to supply hot water and a heat insulation control part 51 brings a heat insulation function into an ON-state. Further, after preparation operation coping with the operation is completed, the heat insulation function is brought into an ON-state. For example, control for automatic operation is effected, after boiling of bath water, from a point of time when a bath is brought into a heat insulation state, the heat insulation function is brought into an ON-state. When a given time commencing from the starting of heat insulation operation elapses or given control is received, or based on detecting information of a given sensor, the heat insulation function is brought into an OFF state.

Abstract: PURPOSE:To prevent the deterioration of material at the edge part of a rolling sheet and to improve the yield of a product, by controllingly heating the edge part of a continuously cast slab by a heating device, installed at the outlet side of a continuous casting machine, in a direct-coupled steel-making-rolling process for directly rolling a continuously cast slab. CONSTITUTION:When the surface temp. at the central part of a slab at the outlet of a continuous casting machine is TS' and the simulated temp. of slab at the inlet of a heating device is TA' and its temp. difference is DELTAT', the simulation temp. is raised up to TS (or lowered) to set the temp. of a slab edge-part at the inlet of heating device to TA+ or -DELTAT. The heating time (t) is fixed from the temp. TB at the outlet of heating device and the set temp. TA+ or -DELTAT at the inlet of the device. When the heating time (t) is set, a combustion zone (zone length) is fixed by using the time (t) as a parameter, to heat the slab under a reference load of burner (:a<1>%). In this case, when the combustion zone is insufficient (zone length is short), the slab edge-part is heated by raising the burner load (b%, for instance) higher than the reference (a%); and further, when the heating is required only by a part of the final combustion zone, the burner load of the combustion zone concerned is lowered than the reference (C% for instance) and the heating time is prolonged, in consideration of energy saving.

Abstract: PURPOSE:To reject alpha ray and alleviate warpage of wafer by forming a silicon nitride film and then a polyimide resin film sequentialaly on the element region of semiconductor substrate. CONSTITUTION:When a silicon nitride film 14 is formed by the PRD method on a silicon substrate 11, a stress by the PRD method works on the silicon substrate 11 in the direction where it elongates, causing the substrate 11 to be warped upward. Then, a polyimide resin is coated in the thickness of 30-100mum on a nitride film 14 and it is converted into the polyimide by the baking. When the polyimide resin film 15 is formed, the polyimide resin is contracted, warping downward the substrate 11. Accordingly, the substrate 11 becomes flat. Thereafter, a resist pattern is formed on the resin film 15, the resin film 15 and nitride film 14 of the bonding pad and scribe line are removed by sequentially etching the resin film 15 and nitride film 14, and moreover element is heated. Thereby, the alpha ray rejecting and protecting film consisting of the silicon nitride film 14 and polyimide resin film 15 can be obtained on the element region 12.
